Abstract

L'invention porte sur un système et un procédé permettant de dissimuler le contenu numérique enregistré sur un support tel qu'un CD, et plus spécifiquement sur un appareil et un procédé d'enregistrement, sur un CD ou autre support par un enregistreur du type CD-R ou CD-RW relié à un ordinateur, permettant de dissimuler le contenu numérique enregistré pour empêcher sa lecture par un lecteur de CD-ROM ou tout autre lecteur numérique ou dispositif ad hoc, comme cela se fait par exemple lorsqu'on extrait (par piratage) des données audio numériques correspondant au contenu musical du CD. L'appareil et le procédé permettent un meilleur contrôle de l'utilisation et de la copie du contenu d'un support physique par un acheteur intermédiaire tout en limitant sa copie, et sa distribution à des personnes non agrées.
